For whatever reason, they built these rigs above the wheel wells. so it looks like it would be tall inside but the reality is the standing room was 5'6". If I was going to live in this rig I needed to be able to stand. I decided I would undertake raising the roof. It involved a ******** ton of weld cutting that was discouraging. Once the roof was dismounted it was smooth, quick sailing. The easiest way I could think of doing the lift was to take 2x6 beams and basically frame a box just past the radius of the roof siding. Then I rewelded each 2x3 back in order like framing a house. Finally, the other time-consuming part was welding around 80ft of seams. All and all it took about 30-40 hours of work. absolutely worth it. It was raised 5.5" and cost $320 in aluminum.
